SPECIFICATION forming part of Letters Patent No. 273,325, datei March e,less,

Application led April 25, 188'2. (Model.)l

llov all whom it may concern Be it known that I, WILLIAM VAN HORN, acitizen of the United States ofAinerica. residing at Piqua, in thecounty of Miamiand State of Ohio, have invented certain new and usefulImprovements in Grain-Binders, of which the following is aspecification, reference being had therein to the accom panyingdrawings.

rIhis invention relates-t0 that class of grainbinders in which the grainis bound with cord and it consists in certain peculiarities andimprovements therein, as will be hereinafter described and claimed.

In the drawings, Figure 1 represents a perspective view taken from thefront, and Fig. 2 a perspective taken from the rear, ot' a grainbinderconstructed according to my improve'- ments. Fig. 3 is a detail View, inelevation, of the rear ot' the machine, wheel K being removed. Fig. 4 isa top plan view, and Fig. 5 Fig. 6 represents in sectional elevation theneedle with my improvements applied thereto. Fig. 7 represents aperspective View ot' the sheaf or gavel compressor. Fig.8 is anelevation of a part ofthe gearing. Fig. 9 is afrontl elevation of myimproved grain-packer. Fig. 10 represents in perspective one ot' mypackera-rms. Fig. 11 represents in perspective a cam and rack wheel foroperating the cord holding and tying mechanism. Fig. 12 represents inelevation the cord-tyer in position in the framing. Figs. 13 and 14represent the cord-tyer and sleeve separately. Fig. 15 shows in rearelevation, and Fig. 16 in plan view, a portion of thc gearing withclutch mechanism. Fig. 17 represents in perspective vthe cord guidingand throwing arms and knife-operan ing arm's. `Fig. 18 represents inperspective the gavel holding or supporting andthe gavel- `dischargingarms. Fig. 19 shows the cord,-

holding device separately. Y A represents the patform or apron uponwhich the grain is recl ived trom the elevator.

This platform may bc secured in any suitable' manner to theelevatorfraine, and is slotted, as shown, to admitof the passagetherethrough of the needle and its attachmentsand the gavel-compressor,and also the gavel holding and discharging arms.

Journaled in bearings c on the under side of the platform A is therock-shaft B. These A,bearings are secured to the platform by ears I,and extend farenough in a downwarddirection at their center to allow ofthe gavel holding and discharging arms revolving within the slots in theplatform without comin-g in contact with shaft B.

C represents the'cordspool, which is journaled in bearings c, secured tothe underside of the platform. Frein this spool the. cord passes to andthrough the stapleV d, and from thence to staples ein thecompressor-pushing arm E, to the needle D, which has a longitudivnalgroove, o?, in its rear face, to guide the cord and prevent it slippingoff the needlepoint, and a stop, a", against which the front end of theU-shaped arm V, to be presently described, impinges, and thereby holdsthe cord straight in proper position to enter the groove a2.

F represents the main driving-shaft, which receives its' motion througha pulley or cog \vheel,f, operated by any suitable means.

The packer Gr, for packing the grain upon the gavel holding orsupporting arms, consists vof two disks or wheels, one of which, H, is

keyed upon the inner end of the shaft F, and has pivoted to its face, atg, the arms or extensions h of the packer-arms l, the other disk, J,being journaled in the framing at i, eccentrically to the disk H, andhaving the ends of the packer-arms I pivoted at k to the inner face ofthe disk J, as shown. lt' desired, instead of-applying the pivot-pinsgand lc directly to the packer-arms, and then securing said pins withinholes in the disks, said pins may be first applied to the disksthemselves, and the packer-arms then. engaged therewith. Again, the arms0r extensions h of the packerarms I may be of elbow form, as shown, orthey may be of any other desired or convenient con. tour 0r shape, andthey may extend from said arms in a reverse or in any other suitabledirection from said arms. The -distance from pivot g to pivot h is equalto the distance from center to center of the disks or wheels H J. Uponeach of the pivot-pins is formed a shoulder, l, which projects slightlybeyond the arms or extensions, to prevent the binding upon and frictionagainst said disks of said packer-arms. By thus eccentrically mountingthe disks H ICL.

and J and constructing the upper ends of the packer-arms I with an armor elbow-extension at their inner ends, and pivoting said arms to eachdisk, and mounting said disks with an equal distance between theircenters and between the pivots g 7:, I secure a uniformity of action ofsaid arms, and as said disks revolve said arms will retain a vertical ornearly vertical position and will revolve around each other, and ontheir upward rotation will be brought entirely within the circumferenceof said disks, thereby insuring the rotation of said arms free fromcontact with any of the operative parts ofthe machine.

By pivoting the packer-arms upon the disks or wheels and mounting saiddisks eccentrically, as shown, considerable leverage power will beimparted to said packer-arms during their rotation forward. rlhis isespecially advantageous when they reach the position for operating uponthe grain on the platform, as they are held perfectly rigid between thedisks, and as they revolve with the disks they press the grain forwardto the holdingarms with a steady force. l

.In the drawings I have shown the binder as provided with one packeronly; but by extending the short shaft or pin t' one or more additionalpackers may be mounted thereon whenever it is desired to exert a forwardpressure upon the grain at more than one point of its length. Looselymounted upon the shaftF is a toothed wheel, m, which is held fromlongitudinal movement upon said shaft by sleeves o, and gears with theteeth of the drive-wheel K, which is keyed upon one end of a shaft, N,upon whose other end is mounted a disk, to be presently described, foroperating the tyershaft and cord holding and cutting devices.

The gavel-discharging arms Xare mounted upon the shaft W. Thegavel-supporting arms L are connected at p to the gavel-dischargin garms X, so as to extend in a reverse direction therefrom, the object ofwhich is that, as the gravel-supportingarms L recede and pass downwardbelow the platform on the completion of the tying of the gavel, saidarms X will ascend and come in contact with the gavel on its oppositeside, and on the continued revolution of said shaft W said arms X willpress the gavel forward and off the platform.

Within the lower end of each arm L isformed a slot, l. `By loosening thescrews p said arms can be slid inward or outward, as desired, to adjusttheir position upon said shaft, and thereby increase or diminish thespace between the arms L and the packers, and allow of gave-is of largeror smaller circumierenc being formed, as desired. f

Upon the inner face of the drive-wheel K isa cam, Y, the rim of which,as the drive-wheel revolves, is in contact with apin, q', on the innertace of the hooked arm M. Upon this disk Y being revolved until therecess 1^ comes under the pin q', said pin.will drop down within saidrecess, and thereby bring the hooked outer end of the arm M intoengagement with the upper arm of the clutch on the wheel m, and therebyhold all the operative parts ot' the machine, with the single exceptionof the packer, from rotation. Upon the grain being packed against thegavel-supportingarmsL by thepacker-arms, said arms will be forcedbackward, and as they are securely fastened to the shaft WV, said shaftW will thereby be correspondingly turned. The reverse rotation of thisshaft W is prevented by a spring-pawl, s', which engages with aratchetwheel, t', upon said shaft W. Upon the end of this shaft Wiskeyed a cog-wheel, L, which meshes with a gear-wheel, n', journaled inthe framing. Projecting from the inner face of this gear-wheel u' is aprojection, o', which, as the gear-wheelu is, through the cog-wheel L,moved around the distance of one tooth, is forced against thedownwardly-depending portion w' of the hooked arm M, pushing the sameforward, and thereby tripping the hook, as shown in dotted lines, Fig.3, and by means of a clutch mechanism, to be presently described,coupling the wheel m with the driving-shaft F, in order that. said wheelm may rotate and impart motion to the drivewheel K and parts connectedtherewith. The horizontal and vertical arms of the hook M have movementwithin staples gZ h2, which retain the same in proper position.

Projecting outwardly from the outer face ofA the gear-wheelul is apin,f2, which rides upon the rim t2 of the disk la?, the oiiice of saidpin while riding upon said rim being to hold the gear-wheel, andconsequently also hold the toothed wheel Z and the shaft upon which arethe gavel supporting and discharging arms, from movement until therecessed orcut-away portion Pof the rim i2 comes opposite said pin f2-Then at this moment the cogs of the gearwheel u andthe teeth of the rackm2 will mesh together, and as the gear-wheel u revolves it will turn thetoothed wheel Z and cause the shaft W to revolve and operate the gavelsupporting and discharging arms. The grain from the elevator falls uponthe platform or apron Ain front of the packer G, and as the cogwheel f,which may be a chain-wheel ora band-pulley,or of other suitableconstruction, and revolved in any of the well-known ways, revolves, theshaft F is caused to revolve and carry with it the innerdisk or wheel,H,which in its turn carries around the outer disk ork wheel, J, and thepacker-arms I, secured to said disks or wheels. As these arms I revolvethey take hold of the grain lying upon the apron or platform A andpropel it forward toward the gavel-supporting arms L, said forwardmovement of the grain being continued by the arms I until the pressureof the grain against the gavel-supporting arms L forces them back farenough to raise the hooked arm M from a clutch-armi), on the inner faceof the gearwheel m. This arm NI is pivoted at its rear end to thefi'aming,and is held down at itsfree end in locking engagement with thearmp of the clutch q, as shown in Fig. l5, by a plate- IOO ' ing coupledtogether, the continued rotation of said shaft will'cause said wheel torevolveand impart rotary motion to the drive-wheel K.

On the outerface of the drive-wheel K, and.

eccentrically thereon, is a stud or project-ion, b2. To this stud b2 issecured the upper end of a pitman, c2, which is composed of two shortrods having rightand left screw -threads formed upon their innerends,.said ends being coupled together by a sleeve, d2, by turning whichin one direction the inner ends of said rods may be brought nearertogether, and the vpitman thus shortened, and by turning said sleeve inthe reverse direction said ends are pushed further apart, and thepitinan thereby lengthened. The lower end of this pitxnan is secured toa crank-arm, e2, whichis keyed upon the outer end of the rock-shaft B.Upon this rock-shaft B is mounted the needle D.

'lhe compressor T consists of two curved arms, U U, joinedtogetheratornearone end by a pin or stud, m', and at the opposite end bya pin or stud, m3. The pin m' preferably has a roller mounted thereon toavoid friction on the needle, and at this end the curved arms ot' thecompressor arepivoted upon a transverse shaft, a', having bearingswithin the platform or withv in slotted plates, o', attached to theunder side thereof. By-securing these ends of the arms U U within theslots 02, the needle, on passing up, will press against the pin m3 andpush such lower ends forward within theslots, thereby diminishing thespace between the compressor and the gavel -holding arms. Upon theretraction of the needle the recessed rear edges m of the arms U ofthecompressor are forced. against the shaft B, which causes their pivotedends to move rearwardly in the slots sufficient ly to allow of such armsU passing down beneath the platform withoutcoming in contact with andbinding against the shaft B, as would be the case were the arms Upivoted without capability of horizontal movement.

E represents a curved arm, which may be formed solid with the needle-armor formed separately therefrom and secured at its lower end thereto. e,as shown, through which the cord passes from the spool to the groove a2and to the eye of the needle, and near its upper end this arm E passesbetweenthe cheeks or arms U ofthe compressor and rests against the rearface of the pin or stud m3. The effect of this arrange-- ment is that asthe drive-wheel K revolves the shaft B is turned, carrying with it theneedle l), and as said needle passes upward and for- This arm has eyesor staples c ward the arm E thereon will press against the pin or studm3 and force the compressor for ward, thereby compressing the grain upto and upon the gavel-supporting arms L, and on the needle beingretracted, after the bundling and tying of the gavel are completed, therearward motion of said needle will cause its arm to press against thefront face of the pin or stud m3 and 'carry the compressor down with itbelow the platform A.

A-ttached to the arm E, or formed solid therewith, with its forward endresting or abutting against a stop at ax x, on the rear of theneedlearm, for the purpose hereinbefore described,

`is a bow or Dshaped arm, V, which serves as a guard or fence to holdback the grain Afrom the needle during the operation of compressing andtying the gavel. As the packer is in constant operation, the tendency ofits arms is to continuously press forward the grain upon thc platform,and without such arm V the grain would be pressed against the needle andcompressor, and thereby impede their action and become tangled up withthe gavel being bound. By the employment of this arm V the grain uponthe platform A is e'ectually kept back from the needle and compressorand a clear Avspace left within which they they can work.

At the same time that wheel K causes the forward motion ofthe needle italso rotates the shaft N, at whose opposite end is secured a cam andrack wheel, 0. Ou therim or periphery of this cam and rack Wheel O is anarm or pin, c, having segment on its outer end, which, when the needlehas passed forward so as to place the end ofthe cord across or'betweenthe arms of the cord-holder .fr by the continued revolution of said camand rack wheel O, comes in contact with-the toothed disk y' and turnsthe cord-holder w around the distance of one arm, thereby causing, thelatter to clamp and I hold the cord taut until the knot is formed, whenthe knife Sis turned by the arm h and the cord cnt and thrown, in themanner hereinafter described.

Projecting from the outer face of the cam and rack wheel O is a lug orprojection, upon which is sleeved a roller, n2.

The cord-tyer l? consists of a shaft, a3, having a finger, a, and asleeve, a5, having a finger, a6. Upon the sleeve a5 is formeda cam. c",which, when the tyer is rotated to form the knot by the segment on thecam 'and rack wheel O engaging with the cog-wheel on the tyer-shaft,rides upon saidroller. The sleeve and its finger a6 are thereby raisedto admit the entrance between thefingers a4 and a6 of that part of thecord at the rear of the knot, and when the olfset als on the cam a7 isin line with the roller n2 the free end of the spring a9, which restsupon the top of said cam, will force thesleeve down, and thereby clampthe cord between the two fingers. This spring is -secured at its rearend by a screw, al, to the IOS said spring increased or diminished as itis desired to force the sleeve down more or less quickly and firmly.

The object of arranging a roller for the camV al to travel upon is thatthereby the tycr may rotate with greater ease and less friction thanwould be the case were said cam arranged to Y ride upon a pin or stud onwhich there was no pendent vertical movement upon said shaft.

Upon the inner edge ol' the wheel() is a segmental rack, y, which is soarranged upon said wheel that it shall gear with the teeth upon thepinion or toothed wheel zon the top of the Iyer-shalt at the time thatthe segment on the pin c on the wheel 0 operates upon the cordholder.The teeth on the segment y are of a number sufficient to revolve thecog-wheel z once. As the cog-wheel z revolves it carries the shaft ofthe tyer I.

A cam-groove, a', is formed in the circumference ot' the wheel O, withinwhich works a pin, b', on one end ot' an arm, Q. This arm Q is centrallypivoted at c to a link, d', connecting said arm Q with arm It, and has apivot or pin, e', which rests within the slotf in the arm 1i. By thisconstruction, upon the revolution ot' the wheel O bringing the pin binto engagement with the inclined portion g of the cam-groove in thewheel O, the arm Q will draw the slotted end of the arm R inward, andconsequently force the front end, h', of the arm R and the hook-shapedend t" outward. As the end It moves outward it comes in contact with thelugj on the knife S and pushes said knife partly around, so that thesharp edge k' otsaid knife shall cnt with a shearing action against theframe on which it is mounted, and thus sever that portion of the cordlying across the edge of the frame and allow ot' the removal of the tiedgavel. As the needle begins its return movement the end 71, of the arm Rreturns to its normal position, and as it returns it comes in contactwith the lug l on the knife S and pushes said knife back in readinessfor the next cutting movement. The hook-shaped end 'i' on the arm Rpushes the cord away after the tying operation.

In Fig. ll is shown a perspective View ofthe cam and rack wheel with apart removed to show its internal construction. The inner face ot' thiswheel has an outer circumferential rim, 2, and inner circumferentialtlat face, 3, recessed at 4, a central recessed portion, 5, and a disk,6, for holding said wheel upon its shaft.

In Fig. 12, 7 represents a plate or disk,which is secured to the framingand lits within or npon the face of the wheel O, (shown in Fig. 1l.) 0nthis plate 7 is aiiat face, 8, with which the ilat face comes in contactand upon which it revolves. 9 represents a central rim which tits withinthe recess 5. 10 represents a circular orifice through which the rollern2 upon the shaft projects to engage with the cam on the Sleeve of thetyer. The opposite face of this plate 7 is recessed to receive thetyer,which is embraced on the opposite side by osets l1 on the plate 12.A recess, 13, is formed in this plate topermit of the free end of thespring agengaging the cam on the tyer-sleeve. Resting upon thetopol'thisplate l2,andextendingacross the rim ofthe plate 7, which is cut awayat that point, as shown,.to allow of the free movement thereof, is adisk, 14, which is mounted on the tyer-shaft and revolves therewith.This disk 14 is cut away or liattened at 15. Upon this plate 7 beingsecured to the face ofthe wheel O, this flattened portion 15 will restagainst the ilat l'ace 3. and, on said wheel() revolving, said face 3will travel continuously across this l'lattened portionuntilthesegnienton the wheel engages with the cog wheel on thetyer-shalt. Immediately on the segment turning the cog or pinion on thetyer-shaft, said disk or collar 14 will revolve, and the circularportion of its rim or edge will then.come opposite to the recess 4 inthe face of the wheel O, and thereby admit ofthe tyer freely revolvinguntil the flattened portion l5 again comes in contact with the ilat face3 of the wheel O.

Attached to the rear end of the framing are two plates, b3 b3. To theinner face of each plate is secured one end of a plate-spring, b4, withits free end extending down toward thelower ends ot' said plates. Thecord holder or wheel an is pivoted within the lower ends ot' theseplates b3, so that its arms w may revolve vertically between the freeends ofthe springs b4. Upon the needle with cord threaded thereonadvancing, the forward portion of said cord will pass across andrestupon said wheel within the space between the arms that is then inalignment with the needle. Then as the wheel() revolves the segment onthe end of the arm of pin c wil engage with the teeth ot' the disk y onthe wheel rv, and thereby turn said wheel around sufficiently to causethe arms w to move forward and carry the cord to and between thefreeends of the springs b4, which will then clamp the cord and hold thesame iirmly between them and the arm holding the cord. The binding orclamping power of said springs b4 upon said cord, and also upon thewheel w, can be regulated by a binding-screw, b", by tightening whichthe plates b3 can be forced nearer together to grip the cord and wheelmore firmly, or by loosening said screw b" the friction upon such cordand wheel can be diminished, as 0ecaslon may require.

Upon the rear face ot' the outer plate, b3, are a spring-pawl andratchet, 118, said ratchet being keyed to the outer end of the shaft orpivot upon which the wheel rotates, for the purpose ot' preventingrearward motion of said wheel which is very necessary, as without somesuch arrangement said wheel might be forced backward, and thereby causethe pre- IIO IIS

273.325 Y l '5 l mature release of the cord held thereby, and thusentanglc the cord and cause a derangement of someof the operative partsof the machine. l

The knife S is pivoted to the outer face of the inner plate, b3, by ascrew, b9. A frictionspring may be placed under the head of said screw,so as to insure the knife being held steadily in whichever position itis turned. This knife has a circular rear edge to allow of the cordreadily slippingaround or across the same on its passage to thecord-holding wheel.

A' represents a plate or shield, attached at each end to suitablehangers on o'r otherwise secured to the framing, for the purpose offending or shielding the tying mechanism from grain. A longitudinalslot, B', is formed in said plate or shield to admit lof the passagetherethrough of the needle-arm and its attachments. y

C, Fig. 2, representsv a bow-shaped arm, which is secured at one end tothe edge of the platform-A and at its outer end to the under sidethereof. As the gavel is pushed off by the arms X it will drop upon thisarm C' and fall away from the line of movement of said arms X.'

The operation of the machine is as follows:

The needle D having been threaded, the pulley or wheelf is connectedothe ordinary driving mechanism, and on motion therefrom being impartedto said wheel or pulley the shaft F will revolve and carry with it thewheel m, and cause the same to revolve the drive-wheel K. By means ofthe pitman c2 motion is then imparted to the rock-shaft-B, upon whichthe needle D is mounted. As this shaft B rocks it carries the needle upand forward until the loose end of the cord is laid across thecordholding wheel. As the wheel O revolves the segment on the pinengages with the teeth on the cord-holdin g disk or wheel w and turnsthe same around, thereby carrying the cord between the cord-clampingplateslf b4, where it is tightly held. The continued revolution of thedrive-wheel will then cause the retraction of the needle below theplatform. Said drivewheel then continues its revolution until the recessr comes opposite the pin q', when said pin q will drop down into suchrecessed portion r and cause the hooked arm M to engage with the arm pon the clutch, and thereby ,hold the coupling-wheel m, and consequentlydrive-wheel K and parts connected therewith, from rotation. Thecordbeing thus placed in position, the grain is then allowed to fallupon the platform A from the elevator in front of the needle, and as thepacker G revolves the arms I press such grain forward and pack it uponthe gavel-supportin g arms L. As the grain packs against thegavel-supporting arms L said arms will be slightly pressed back. Thiswillcanse the shaftto turn partly around and move the wheel t one tooth.As wheel t moves'around the distance of one tooth it causes thegear-wheel u to move the distance of one tooth also, and thereby bringthe pin on its outer face into frictional contact with the rim t2, andat the` same time causes the pin fz on the opposite side of said wheel uto press against the lower end of the arm M, rand thereby raise thehooked end of said arm and release the clutch. The clutch having .thus

been released, the wheel 'm revolves and imparts motion to thedrive-wheel K, which in turn rotates the shaft upon which the cam andrack wheel O is mounted and operates the rock-shaft B, carrying theneedle-arm and its attach ments. As the shaft revolves the needleascends and carries forward the compressor, which compresses the grain,places the cord across the fingers of the tyer, and'presents the forwardportion of the threaded cord to the arms w. At the same time the segmenton the arm u engages with the cog-wheel on the disk w and causes thearms w to move around one step to grasp the cord. Vhile this operationis being effected the segment on the wheel O engages with the cog-wheelor pinion on the top of the tyer-shaft and causes the tyer to rotate andknot the cord. As thetyer rotates, the cam upon the tyer-sleeve comes'incontact with the roller projecting from the wheel O, and rides upwardthereon, thereby opening the respective ngers on' the tyershaft andsleeve, and allowing` them as theyr revolve to pass on either side ofthe cord. The tyer having made one complete revolution,

the sleeve drops down, being aided in such downward movement by thespring pressing upon the top edge of the cam on said sleeve, and holdsthe cord between the two iingers. The cam-groove in the wheel O thenoperates on the arm R and pushes the finger at the front end, h.,against the lug or projection on the knife, thereby causing said knifeSto turn and cut the cord. movement ot' the front end of the arm R then.causes the hook i' to push the cord away and free it from thetyer-hooks. Then, as the drivewheel continues its rotation, the armR isreturned to its position of rest, the needle and compressor areretracted, the shafty W is rotated, and the gavel-supporting andgavel-discharging arms are revolved, and the bound gavel pushed oft' theplatform.
